Hammerhead is Solace's half of 2004's Blackmarket/Hammerhead split EP, re-released in 2006 on limited edition 10 inch vinyl.

Recorded at New Alliance Studios in Boston, MA, Hammerhead found Solace "experimenting with some new styles to nice effect".

[1] Two cover songs - a title track originally by Rare Bird and Link Wray's Rumble - were described as "bombastic",[1] "on fire",[2] and sounding "like some New Wave of British Heavy Metal classic".

[3] An original track ("Cement Stitches") harkens back to Solace's Punk and Hardcore roots [4] with "cool harmonic breakdowns"[3] and vocals "that can go from a solemn Ian Curtis baritone to a wailing Chris Cornell banshee shriek".

It is commonly believed that the intensely personal nature of vocalist Jason's lyrics prevent him from allowing their publication.
